Function from_bytes

pub fn from_bytes<'a, T>(s: &'a [u8]) -> Result<(T, &'a [u8])>
where
    T: Deserialize<'a>,

Return a deserialized value and trailing bytes.

Example

Simple Usage:

let serialized = to_bytes(value).unwrap();
// Ignore the size
let (new_value, _trailing_bytes) = from_bytes::<T>(&serialized[4..]).unwrap();

assert_eq!(value, new_value);

Replace T with type of value.

More complicated one (sending over socket):

let buffer = [0, 0, 0, 4];
let (size: u32, _trailing_bytes) = from_bytes(&buffer).unwrap();

let buffer = [0, 0, 4, 0];
let (val: <T>, _trailing_bytes) = from_bytes(&buffer).unwrap();

Replace T with your own type.
